Flavor with finely chopped orange zest taking care to take only the external part rich in oils.
Bring to the boil without stirring and, when the mixture begins to darken, add the sesame seeds all at once.
Mix for a minute with a wooden spoon to form a single dough.
Being very careful not to burn yourself, pour the mixture onto a sheet of baking paper.
Cover with a second sheet of paper and flatten with a rolling pin until you obtain a single 3-4 mm thick sheet.
Let it cool and set, then trim the irregular edges and cut many bars of about 8 cm x 4 cm.
Let it cool completely. Enjoy!
